.PINION-HOUSING FOR ROLLING-MILLS.

SPECIFICATION forming part of Letters Patent No. 730,205, datedJune 2, 1903.

Original application filed December 23. 1898, Serial No. 700,186. Divided and this application filed February 4, 1903. Serial No. 141,818. .(110 model.)

To all whr-rm it may concern.-

Be it known that I, VICTOR E. EDWARDS, a citizen of the United States, residing at Worcester, in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Pinion-Housings for Rolling-Mills, of which the following is a specification, accompanied by drawings forming a part of the same, in Which Figure 1 represents a front elevation of a pinion housing embodying my invention. Fig. 2 is an end view of the pinion-housing. Fig. 3 is a vertical sectional view through the center of the pinion-shaft bearings. Fig. 4 is an end view of the housing with the pinions removed therefrom.

Similar figures of reference refer to similar Referring to the accompanying drawings, 1

denotes the pinion-housing embodying my invention and containing pinions by which the rolls in the housings 2 and 3 are connected together, the pinion-housing being placed intermediate between the pairs of rolls journaled in the housings 2 and 3. The pinionhousing 1 contains the pinion-shafts at, 5, and 6, placed one above the other, with the upper and central shafts in alinement with the shafts of the rolls in the housing 2 and with the central and lower pinion-shafts in alinement with the shafts of the rolls in the housing 3. The upper pinioneshaft 4 is geared to the central'pinion-shaft 5 by gears 7 7 on the shaft 4, engaging gears 8 S on the central shaft 5, and the lower pinion-shaft 6 is connected with the central pinion-shaft 5 by a gear 9 on the lower shaft 6, engaging the gear 10 on the central shaft 5.

The pinion-housing 1 consists of a pair of upright posts 11 11, preferably integral with the base 12 and inclosing a vertical slot 13 sufliciently wide to receive the journals of the pinion-shafts. The vertical posts 11 11 are provided on opposite sides of the vertical slot 13 with recesses 14, adapted to receive annular journal-bearings 15. The journalbearings 15 are provided on their outer ends with cars 16, which overlap the postsll and are attached thereto by bolts 17, which pass through slightly-elongated holes in the ears 16 and are screwed into the vertical posts 11; The pinion-housing is stiffened by bolts 18, which connect the upper ends of the vertical posts 11 and are arranged to draw them toward each other, so as to pinch the annular bearings 15 in the recesses 14., and thereby securely hold them from movement. By

clamping the annular bearings 15 in the curved recesses 14 I also determine the spacing or distance between the centers, of the bearings.

By loosening the tightening-bolteilS and withdrawing the bolts 17 the annular boxes may be withdrawn from-the ends of the pinion-shafts, and by removing the bolts 18 the pinion-shafts 6 may be "lifted out of'the vertical slots 13.

What I claim as my invention, and desire to secure by Letters Patent,is

1. The combination of the pinion-housing consisting of two vertical postsforming the opposite sides of the housing, each pair of posts inclosing a vertical slot to receive the journals of a series of pinion-shafts, annular journal-bearings held by said posts, and a. series of pinion-shafts journaled in said bearings, said posts having circular recesses inclosing a portion of the peripheries of Said annular bearings, substantially as described.

2. A pinion-housing comprising posts having vertical slots 13, to receive the journals of a series of pinion-shafts and having recesses 14 in the sides of said slots to receive annular journal-bearings, a series ofannular bearings 15, provided with ears 16, bolts 17, by which said ears are connected to the housing and a series of pinion-shafts journaled in said annular bearings, substantially as described.

3. The combination in a pinion-housing of two vertical posts having a common integral base, and inclosing a vertical slot; provided with recesses in the sides of said slot 1.0 receive journal-bearings, and tightening-bolts, connecting the tops of said posts, whereby they are clamped against the journal-bearings held in said recesses, substantially as de- 10 scribed.

Dated this 2d day of February, 1903.
